Mobile gravel production line

The mobile gravel production line is famous for its "mobility, small size and high efficiency". It has two types of movement: tire type and crawler type. The mobile gravel production line configuration can be applied to various materials, including ores, rocks, river pebbles, construction waste and other materials with different hardness. It has a large crushing ratio and uniform output particle size.

1.Core configuration solutions and applicable scenarios

1.Single machine combination solution

Equipment composition: single mobile impact crusher or heavy hammer crusher (integrated feeding, crushing and screening functions).

Applicable scenarios: processing of medium and low hardness materials such as limestone and construction waste, with less site restrictions.

Performance parameters: 100-550 tons per hour.

Advantages: One-time molding, saving 40% of equipment investment costs, but limited hard rock processing capacity.

2. Two-in-one combination solution (recommended)

Equipment composition: jaw crusher (coarse crushing) + cone crusher/impact crusher (medium and fine crushing) + vibrating screen.

Applicable scenarios: Crushing of hard rocks such as granite and basalt, and complex materials that require multi-stage crushing.

Performance parameters: 100-650 tons per hour.

3. Three-unit combination solution

Equipment composition: one crawler jaw crusher, one cone crusher, and one vibrating screen.

Applicable scenarios: large mines or complex terrains that require frequent transfers (such as open-pit mines).

Performance parameters: 100-1150 per hour, flexible movement, and high degree of automation.

4. Modular pre-installation solution

Technical features: prefabricated support platform and components (such as I-beam welded structure, concrete prefabricated blocks), quick assembly on site, no concrete foundation column required.

Applicable scenarios: projects with short mining cycle and rapid production, reducing infrastructure construction time by more than 80%.

2.Process Optimization Design

1. Conventional process:

Coarse crushing: jaw crusher to 80-140mm.

Medium and fine crushing: cone crusher/impact crusher to target particle size (such as 20-40mm).

Screening: vibrating screen classification, closed-loop circulation of substandard materials.

2. Flexible mode:

Screen first, then crush: For scenes with many small materials (such as construction waste), qualified materials are screened out before crushing, increasing production capacity by 80-120 tons/hour.

Truck-free transportation system: With conveyor, direct screening and transportation, reducing energy consumption and dust emissions.

3.Key Technology Advantages and Innovations

1. Modularity and quick installation

The K-series tire truck does not need to cast concrete foundation on site, saving construction time.

The hydraulic outriggers of crawler equipment automatically touch the ground and can be moved by remote control.

2. Intelligent and environmentally friendly design

The remote electronic control system supports monitoring operations in harsh environments (high and low temperatures).

The dust suppression device is integrated or the closed conveying design meets strict environmental standards.

3. Energy saving and cost control

The oil-electric dual-use power system adapts to the environment without electricity, and the comprehensive energy consumption is reduced by 25% compared with the fixed line.

The modular design reduces the difficulty of maintenance, and the lubrication system is optimized to extend the life of the bearing.

4.Typical cases

1. 350-450 tons per hour mobile granite crushing production line in Sumatra, Indonesia

2. 180 tons per hour construction waste recycling project in Jinan, Shandong

3. 200 tons per hour limestone mobile production line in Lang Son Province, Vietnam

4. 1,200 tons per day granite mobile crushing and sand production line site in South Africa

5.Precautions and modification suggestions

1. Material adaptability

When the soil content is too high, it is necessary to modify the pre-screening (such as blocking the screen plate, adjusting the feeder inclination), or add soil removal equipment at the front end.

2. Maintenance and production improvement modification

Optimize the spring stiffness of the vibrating feeder (test 170-230kN/mm combination), increase the amplitude and material flow rate.

3. Environmental compliance

Choose a model equipped with dust suppression device or closed conveying to avoid excessive dust.
